Embodiment 1

[0026] Example 1: See Figure 1-2 , the present invention provides a technical solution: a non-contact high-precision real-time identification method for explosives, comprising the following steps:

[0027] S1: Install the detector and conduct fixed-point detection through the detector. The detector has an explosives information collection module 1, an identification processing module 2 and an early warning module 3. The explosives information collection module 1 is a millimeter-wave radar and a detection and identification camera;

[0028] S2: The explosive information collection module 1 collects the image information at the base point and the millimeter wave information emitted and reflected by the detected target, and transmits the above information to the identification processing module 2;

[0029] S3: The identification processing module 2 processes the information in real time, and outputs the identification information to the early warning module 3 in real time during...

Embodiment 2

[0032] Example 2: See Figure 3-4 , in this embodiment, the detector includes a walkable support 4, a mount 5, a radar body 6 and a rotating camera structure, the top of the walkable support 4 is connected to the mount 5, and the end of the mount 5 is equipped with a radar body 6 , Rotating camera structure; the walkable support 4 includes a fixed base 401, a first screw 402, a wheel frame 403, a first connecting rod 404, a column 405 and a first drive assembly, and the bottom end of the fixed base 401 can be fixed at a fixed point by bolts At the detection point, a first screw 402 and a column 405 are installed at the end of the fixed base 401 , and the first screw 402 is movably connected to the top of the fixed base 401 and the bottom of the mounting base 5 through a rotating shaft.

[0033] In this embodiment, the transmission gear 406 and the first screw sleeve 407 are set on the first screw rod 402, the end of the first screw sleeve 407 is hinged with the first connectin...

Embodiment 3

[0038] Example 3: See Figure 5 , in this embodiment, the camera mounting plate 12 is equipped with a camera assembly, the camera assembly includes a housing frame 121 and a camera body 122 installed at the end of the housing frame 121, and a protective cover unit is installed on the housing frame 121; The cover unit includes two protective cover bodies 123 and a third drive assembly. The two protective cover bodies 123 are arc-shaped and are arranged on the upper and lower sides of the third drive assembly. The ends of the two protective cover bodies 123 can extend out of the shell frame. 121, a rack 124 is provided at opposite ends of the two protective covers 123; the third drive assembly includes a third motor and a first gear 125 connected to the shaft end of the third motor.

[0039] In this embodiment, the protective cover provided on the rotating camera structure can play a rain-proof and sun-shading effect, preventing the camera inside the camera from overheating and ...

Abstract

The invention belongs to the field of explosive detection and identification, and particularly discloses an explosive non-contact high-precision real-time identification method, which comprises the following steps that a detector is installed and fixed-point detection is carried out through the detector, wherein the detector is provided with an explosive information acquisition module, an identification processing module and an early warning module, and the explosive information acquisition module is a millimeter wave radar and a detection identification camera; the explosive information acquisition module acquires image information at a base point and millimeter wave information emitted and reflected by a detected target, and transmits the information to the identification processing module; and the identification processing module processes the information in real time and outputs identification information to the early warning module in real time during processing, and the early warning module carries out judgment and early warning based on the identification information. The detection and recognition method is based on image recognition and millimeter wave detection and is matched with the neural network, so that the hidden dangerous goods detection and recognition capability of an effective distance is provided.

Description

technical field [0001] The invention relates to the field of detection and identification of explosives, in particular to a non-contact high-precision real-time identification method for explosives. Background technique [0002] Terrorists have been active all over the world with various harmful activities for many years, among which explosive damage is also showing an increasing trend. With the increase of various terrorist activities, the difficulty of preventing terrorist attacks is also increasing, which puts forward an urgent demand for explosive detection and explosion-proof measures. Explosives detection is an extremely important means of anti-terrorism. Focusing on the development of new explosives detection equipment and technology, and vigorously improving the effectiveness and reliability of explosives detection can contain terrorist activities in an attempted state. [0003] The traditional detection of explosives is mostly carried out manually, which makes the ...
